1. Catch some jazz in the park
4:30 p.m.: The Loyola Jazz Alumni Jam will play at the Newman Bandstand, on the Magazine Street side of Audubon Park. Bring a picnic — or buy food on site — and a blanket or chairs. Free.
2. Do a good deed
9 a.m. to noon: Teams will fan out in Metairie, New Orleans and the North Shore for the 25th annual Lake Pontchartrain Foundation Beach Sweep. Those who can’t make it to the water’s edge are encouraged to tend to their storm drains. Call (504) 836-2238 to register.
3. Tailgate before the game
In Champions Square, the Brass-A-Holics rev up fans with an outdoor concert before the Saints-Vikings home opener while the Dome debuts Opening Act, its new sports bar. Open before, during and for one hour after the game, you’ll find 30 TVs plus food and drink options. Admission is free.
